The robber who killed a pregnant woman cleaning Eclipse Gentlemen's Club last weekend had to be familiar with the strip club, manager Rozbeh "Ross" Sakika remembered thinking.

The robber did not touch thousands of dollars in music equipment or anything in the dressing room or office drawers of the club on South Gessner. Only two of the three cash registers packed with 1,000 $1 bills were slammed against the floor. Management always left the third empty, at the end of the night, he said.

Police found no signs of forced entry. Maria Lucrecia, who had for two years cleaned the strip club before its opening, was insistent about only unlocking the door for people she knew, Sakika said, recalling how she did not allow him in on his first day until the owner called to say it was OK.

So who could know exactly where to find the money and convince Maria Lucrecia to unlock the door?

'This guy's crazy'

Osvaldo Fernandez-Aguilar - who worked security at the club - was charged with capital murder in the fatal beating and choking of Lucrecia, 27 years old and five months pregnant, according to a Houston Police Department news release. He remains at large and police are asking anyone with information about his whereabouts to call Crime Stoppers.

Fernandez-Aguilar, who Sakika said was employed by Houston Contract Patrol, helped open up the club every day for more than a month and was one of a few people who knew where the cash was kept. He said the club has stopped doing business with the security company, which they believed performed complete background checks on its employees. Fernandez-Aguilar had two prior misdemeanor theft convictions, according to court records.

"I guess she figured he had came in early. He had known I don't get here until 6 and he would have time," Sakika said at a news conference Sunday, turning to look straight into the television cameras. "For you to kill a lady you knew every day, for you to kill her like that and walk out the club like nothing's wrong - I don't understand that."

Sakika said he had socialized with Fernandez-Aguilar outside of work with other employees.

"We hung out after work and would say, 'Man, this guy's crazy,'" he said. "But not thinking anything would happen seriously. He liked to have fun and everything. I personally knew he liked to fight."

Complaints lodged

On his cellphone, he had recorded a video of Fernandez-Aguilar in a fist fight while working outside the club. As manager, he had fielded numerous complaints from customers. Three weeks before the robbery and murder, the strip club told the security company they did not want Fernandez-Aguilar working there anymore, Sakika said.

He still came around the club to hang out with friends. The day before the robbery, Fernandez-Aguilar had asked each of his old co-workers for a $100 loan to help him get by while he looked for a new job, Sakika said.

The next day, he is accused of killing Lucrecia and stealing the strip club's cash. Security footage from a nearby business showed him carrying a bag of takeout food as he walked away from the door and passed Lucrecia's husband.

'We were very shocked'

Lucrecia normally brought her 5-year-old son to work with her, Sakika said, but that day her husband had taken the boy out to eat. When he could not reach his wife on her cellphone, they returned. She did not answer the door.

A manager arrived and walked inside with the family, finding her beaten body on the floor.
